Two F-15s Join NASA’s Quesst Program – Civilian Supersonic Test Bed
Bottom line up front: NASA has taken two retired F‑15 fighter jets, fitted them with sensor suites, and rolled them into the Quesst (Quiet Supersonic Transport) research program to help shape the next generation of civilian supersonic aircraft.

Design & Looks
The F‑15’s iconic twin‑engine silhouette hasn’t changed much, but NASA’s makeover is all about data, not dogfighting. Engineers stripped out combat‑ready avionics and installed a modular sensor pod under each wing. The pods carry high‑speed pressure transducers, acoustic microphones, and infrared cameras. Visually, the jets still look like the sleek, angular birds that dominated the skies in the 1980s, but the added gear gives them a slightly bulkier profile that hints at their new scientific purpose.
Performance & Mileage
Even with extra equipment, the F‑15’s performance remains impressive. Each aircraft still pushes past Mach 2.5, and the added sensors only shave a few percent off top speed. The range—about 3,450 km (2,145 mi) with external fuel tanks—means the planes can cruise at supersonic speed over long test corridors without frequent refueling stops. This range is crucial for NASA’s Quesst trials, which need consistent data over hundreds of miles of airspace.
| Engine | Mileage (Range) | Price (Approx.) | Top Features |
|---|---|---|---|
| 2× Pratt & Whitney F100‑PW‑229 | ~3,450 km (2,145 mi) | ~$100 million each |

Price & Rivals
At roughly $100 million per airframe, the F‑15 isn’t cheap, but NASA isn’t buying them for profit—just for a proven platform that can survive the stresses of repeated supersonic runs. The only real rivals in this niche are purpose‑built supersonic testbeds like the Boeing 747‑SF and the Airbus A380‑X. Those aircraft cost far more and lack the agility of a fighter‑derived jet. By repurposing the F‑15, NASA saves money while gaining a fast, maneuverable test platform.
FAQ
- What is the range of the NASA‑modified F‑15?
The sensor‑equipped F‑15 can travel about 3,450 km (2,145 mi) on a full fuel load, allowing long‑duration supersonic flights for data collection.
- Why did NASA choose the F‑15 for Quesst?
The F‑15’s proven high‑speed performance, robust airframe, and twin‑engine reliability make it a perfect, cost‑effective testbed for quiet supersonic research.
- Is the Quesst program aiming for commercial passenger jets?
Yes. Quesst gathers acoustic and aerodynamic data to design future civilian supersonic aircraft that meet modern noise regulations and fuel‑efficiency goals.
